PPROF diagnostics showed that a polar choke set in 2017 had failed. A subsequent polar choke set in July 2021 successfully isolated majority of gas in toe section but well would no longer flow to the high pressure header afterwards (well is a straight shot to GC3 with no LP access). Additional zone 1A perfs will be shot to bring in more competitive, low GOR production and allow well to flow to HP. Objective:Add perforations in zone 1A to increase fluid rates and allow well to flow to HP fulltime. Slickline 1. MIRU SL unit and pressure test 2. RIH and pull/reset a deep (Station #2 at 8014’ MD) kickoff GL design per GL Engineer. 3. RDMO Sundry Procedure (Approval Required to Proceed): Note: The well will be killed and monitored before making up the extended perfs guns. This is generally done during the drift/logging run. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head.

Assure excess fluids available if needed to keep hole full. 10. Confirm well is dead. Bleed any pressure off to returns tank. Kill well w/8.4 ppg 1% KCl or equivalent as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is reestablished. 11. Pickup safety joint and TIW valve and space out before MU guns. Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. 12.

Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00) Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and ND for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing,Gas Lift, Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain).

Test separator Mud Program: • Well kill: 8.4 ppg brine. • Milling/drilling: 8.6 ppg PowerVis for milling window and drilling (686 psi over-balance). - Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. • Hole size: 4.125" Liner Program: • 3-1/4", 6.6#, L-80, TC-Il Solid Liner 9,500' MD — 10,500' MD • 2-7/8", 6.5#, L-8' Solid Liner g,4 �` 10,500' MD — 12,510' MD • A minimum o'iliFirs of 15.8 ppg cement will be used for liner cementing. (TOC 9,500' MD) • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional • See attached directional plan. Maximum planned hole angle is 92°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 24,145'. • Distance to nearest well within pool — 150' (C-03). Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCUMCNL logs will be run. - Perforating: • SWS 2", 6 spf, perf guns, 1-'/a" CSH work string, & 2-3/8" PH6 • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Anti-Collision Failures • C-13 center to center distance: 167' status: plugback • C-13A center to center distance: 539' status: active producer Hazards • The maximum recorded H2S level on C Pad w 38 ppm on well C-33 on 4/16/2011. Reservoir Pressure • The reservoir pressure on C-03C is expected to be 3,250 psi at 8,800' TVDSS. (7.1 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,370 psi. _ • An EMW of 8.4 ppg for this well will provide 595 psi over-balance to the reservoir.
